This invention relates in general to security and anti-theft devices, and more particularly, to a security device for a hinged electronic product or device to prevent theft of such item.
In order to deter and prevent the theft of various hinged electronic items such as laptop computers and portable DVD players and the like from offices, houses and other establishments, various security devices and systems have been developed. One known security device comprises a bracket assembly that captures the laptop about its hinge and is fixedly attached to a table or other object to prevent movement of the hinged device. It is also known to use a cable that encircles the hinge in place of the brackets. While such devices may work, the brackets and cable are often cumbersome and are not aesthetically pleasing (e.g., for use in store displays). Furthermore, use of the bracket assemblies or known cables substantially prevents movement of the laptop. Accordingly, such devices are not favored by retailers and other business establishments who desire the product to be picked up and examined by potential purchasers, in as close to actual use conditions as possible.
It is also known to use a detector that is screwed into the video port, wherein an alarm goes off if anyone tries to unscrew the detector. However, it is desired to eliminate the need for having to screw a detector into the video port. Yet another known device utilized an electronic sensor that would go off if one tried to remove the cable from the hinged device. While these systems may work, they were not well received by the business community because they lacked a mechanical tether.
Additionally, it has been known to use a KENSINGTONĀ® port that utilizes a security cable having a loop at one end such that, after the cable is wrapped about an object, the other end of the cable may pass through the loop and be attached to the KENSINGTON port on the computer. However, such systems permit the computers to be stolen by breaking off part of the computer about the KENSINGTON port, thereby leaving the laptop housing damaged, but not affecting the operability of the computer.
Therefore, there is a need to produce a security device capable of protecting against theft of a hinged electronic device, while permitting movement and use of the electronic device, and which addresses the problems with the prior systems and devices, without damaging the hinged device.
The present invention is an improvement over the prior security systems in the way that the security device protects a hinged product such as a laptop or portable DVD player. In one embodiment, the security device of the present invention comprises a band or plate having a height that permits it to extend through the open area about the hinge of a hinged electronic product (i.e., the area between the screen and the body). Anchor assemblies fixed or attached to both ends of the plate are sized so that they (and thus the plate) may not be pulled through the hinge. In particular, a first anchor assembly may include a bottom and top half that collectively include a male member and a corresponding female member that can extend through a slot on the end of the plate. Once the halves of the first anchor assembly are attached together (e.g., by ultrasonic welding), the first anchor assembly is thus fixed in place relative to the plate.
A hole extending through the plate is sized to receive the elongated body of a fastener for connecting the plate to the second anchor assembly. The second anchor assembly may include a base and a lid assembly that may be attached together by a pair of fasteners and that include a slot for receiving the plate. In one embodiment, the lid assembly includes a pair of holes that have an upper portion sized to permit the head of the fastener to be recessed within the bottom of the lid assembly. The lower portion is sized so that the fastener head may not pass therethrough. Accordingly, once the plate is inserted into the corresponding slot of the second anchor assembly, the plate will cover and prevent access to the fastener heads.
A tether extends from the second anchor assembly to securely attach the security device and hinged electronic product to an object, thereby allowing the hinged electronic product to be securely moved a limited distance. The tether may comprise one or more wires for electronically attaching the security device to an alarm system to, among other things, set off an alarm when the tether is cut.
In order to detect the presence of the plate, the second anchor assembly may include a lever switch so that insertion of the plate into the slot of the second anchor assembly depresses the lever to complete an electrical circuit and arm the device. Subsequent attempted removal of the plate acts to open the circuit and activate the alarm.
The security device may also include a sensor attachable to the hinged electronic product to detect attempted removal of the security device from the hinged product. In one embodiment, the sensor comprises a sensor housing having a button extending outwardly from its bottom and that is depressed when attached to the surface of the hinged product to complete an electrical circuit. The bottom of the sensor includes an adhesive sheet to adhere to the surface of the hinged product. A release liner may be placed over the adhesive sheet when not in use to protect the adhesive sheet. In operation, depression of the button when the sensor is placed onto the surface of the hinged electronic product acts to close the electrical circuit. An indicator (e.g., an LED) associated with the sensor may then indicate that the sensor is armed. Attempted removal of the security device and/or the sensor that causes the sensor to be removed from the surface of the hinged product will open the circuit and activate an alarm in the form of a visual (e.g., an LED) and/or audio response.
A circuit board may be located inside the anchor assembly to assist in monitoring the status of the security device. In one embodiment, the circuit board is an intelligent device that may be connected to and monitor resistance of the lasso assembly or cable to determine when it is tampered with or cut. A LED on or associated with the lasso may be operatively connected to the circuit board to flicker, blink, indicate or otherwise indicate tampering with the lasso assembly.
The second anchor assembly may also include at least one electrical circuit for detecting the attempted removal or tampering with the security device. In one embodiment, the plate may include a pair of electrical contacts that are connected to an alarm system through filaments and corresponding contacts. When the fastener is inserted through the hole in the plate to attach the plate to the second anchor assembly, the head of the fastener or a washer engages the pair of electrical contacts to form an electrical circuit. Removal or attempted removal of the fastener re-opens or breaks the electrical path between the pair of contacts, which can be detected by a security or alarm system. The aforementioned electrical circuit or another electrical circuit may also be operatively attached to an indicator such as a light emissive device (e.g., an LED) to indicate when the security device is armed. The plate may also include filaments that detect when an attempt is made to cut the plate and trigger a visible and/or audible alarm.
In an alternate embodiment, the plate may include raised portions that engage brush-type contacts located in the second anchor assembly when the plate is inserted into the second anchor assembly to complete an electrical circuit for indicating that the system is armed and detecting the removal of the plate from the second anchor assembly.
Alternatively, the security device may utilize a cable that may extend about the hinge and be secured to an anchor assembly through a plurality of slots. In one embodiment, the cable comprises a singular cable that includes a pair of straight sections that are spaced apart a distance to align with corresponding slots on the anchor assembly. The straight sections are joined together at one end by a curved member so that when the cable is secured by a screw or other fastener in the anchor assembly and the curved member prevents the cable from being withdrawn without removing the fastener. At the other end of the straight sections are curved portions that permit the ends of the cables to extend substantially parallel to the straight sections so that they also may be placed within the respective slots on the front side of the anchor assembly. End members having a diameter or width that is greater than the width of the respective slot are preferably attached to the ends of the cables to prevent the ends from being withdrawn once operatively connected to the anchor assembly. The curved portions of the cable are sized and shaped so that the hinge member of the computer or other device fits therwithin.
It is therefore an object of the present invention to provide a new and improved security device for use in the prevention of theft.
Another object of the present invention is to provide a new and improved security device that permits movement of a hinged product.
It is yet another object of the present invention to produce a security device that is economical and easy to manufacture and use.
Other objects, features and advantages of the invention will be apparent from the following detailed disclosure, taken in conjunction with the accompanying sheets of drawings, wherein like reference numerals refer to like parts.
